Case statement in a view – Fail!
Well I can’t recall when (and why) but one time I was writing a view in a Rails project and needed to write a case statement (of course I could have done it with usual if / else /elsif statement, but the case statement seemed more natural). My first try (and I remember I was pretty confident that this was the way to go) had gone like this:
# my_view.html.erb <% case params[:animal] %> <% when "dog" %> <p>Barf!</p> <% when "cat" %> <p>Meow!</p> <% end %>
Then the pretty sweet compile error page came screaming at me.
Case statement in a view – Success!
A few minutes later I have found out that the right syntax to write a case statement in a view is:
# my_view.html.erb <% case params[:animal] when "dog" %> <p>Barf!</p> <% when "cat" %> <p>Meow!</p> <% end %>
Hope I helped with this quick little tip!
I’ve completely forfeited using the case statement on views, but you just made my day sir :P
Thank u! it work :)
